Weird that MLB players are using Boldenone =
Equipoise; a veterinarian anabolic steroid primarily used to treat horses. Lol
From my understanding, it's similar to testosterone with a small modification making it a little less androgenic & estrogenic. But it has a long half-life (14 days) & can be detected
up to one year after a last use.
It is not popular with bodybuilders, and it should not be popular with baseball players, either.

Historically, most of the anabolic steroid pops in MLB have been for
Winstrol - an oral compound extremely popular with T&F athletes, bodybuilders, powerlifters, and has a short detection window.
